Optimal Combination of Tensor Optimization Methods [PDF]
, 2020 We consider the minimization problem of a sum of a number of functions having Lipshitz p-th order derivatives with different Lipschitz constants. In this case, to accelerate optimization, we propose a general framework allowing to obtain near-optimal oracle complexity for each function in the sum separately, meaning, in particular, that the oracle for ...

Journal of the Royal Statistical Society Series B: Statistical Methodology, 1989 SUMMARY Optimal screening methods from a predictive point of view and a decision theoretical approach are devised and are shown to have a similar form. In the multivariate normal case the optimal screening region is found to be a quadratic function of the screening variables. The results are illustrated by an example.

Optimization of traffic light phases at adjacent intersections [PDF]
ITM Web of ConferencesThe article studies the relationships between the time intervals of traffic light phases and intersections. Traffic light objects can be mutually useful in relation to each other if they are correctly adjusted and the existing load is distributed.

A general decomposition theory for the 1-2-3 Conjecture and locally irregular decompositions [PDF]
Discrete Mathematics & Theoretical Computer Science, 2019 How can one distinguish the adjacent vertices of a graph through an edge-weighting? In the last decades, this question has been attracting increasing attention, which resulted in the active field of distinguishing labellings.

Hyper-Heuristic Approach for Tuning Parameter Adaptation in Differential Evolution
AxiomsDifferential evolution (DE) is one of the most promising black-box numerical optimization methods. However, DE algorithms suffer from the problem of control parameter settings.

Dynamic programming in package Mathematica [PDF]
ITM Web of ConferencesDynamic programming (DP) is a powerful algorithmic technique for solving optimization problems by breaking them down into simpler subproblems. This paper presents an implementation of DP algorithms for two classic optimization problems: the Knapsack ...

Accelerated Methods for NonConvex Optimization [PDF]
SIAM Journal on Optimization, 2018 We present an accelerated gradient method for non-convex optimization problems with Lipschitz continuous first and second derivatives. The method requires time $O(ε^{-7/4} \log(1/ ε) )$ to find an $ε$-stationary point, meaning a point $x$ such that $\|\nabla f(x)\| \le ε$.

Optimization Methods for In-Line Holography [PDF]
SIAM Journal on Imaging Sciences, 2018 We present a procedure to reconstruct objects from holograms recorded in in-line holography settings. Working with one beam of polarized light, the topological derivatives and energies of functionals quantifying hologram deviations yield predictions of the number, location, shape and size of objects with nanometer resolution.
